Amidst threat of major nuclear accident in Japan, people are in a state of panic worldwide said Jerrold Bushberg, a medical physicist at UC Davis. Bushberg said Americans do not have a good knowledge of the science of radiation and tend to over-exaggerate the risks.
Women who have breast cancer on their left side present a particular challenge to radiation oncologists. Studies have shown that the risk of heart disease is higher in this group of women after radiation treatment because it can be difficult to ensure that a sufficient dose of radiation is delivered to the left breast while adequately shielding the heart from exposure.
Using the new device, physicians monitor patients' angiograms and control exam table movement from behind a lead plastic shield. A newly developed extension bar allows the physician to remain safely behind the shield and still retain table control for panning, according to Martin Magram, MD, developer of the new technique and assistant professor in the department of diagnostic radiology.
"The Canadian Association of Radiation Oncology ( is the voice for specialists in Canada who treat patients' cancer with radiation. In that capacity," explains Dr. Matthew Parliament, president of CARO-ACRO, "we work with proven, controlled, targeted application of various forms of radiation therapy to treat and cure cancer."
It's a sound that saves. A "real-time" radiation monitor that alerts by beeping in response to radiation exposure during cardiac-catheterization procedures significantly reduces the amount of exposure that medical workers receive, UT Southwestern Medical Center researchers found.
A new study says that workers in the nuclear industry who are exposed to chronic low doses of radiation have a slightly higher risk of developing cancer.
In the wake of the failed attempt by would-be bomber Umar Farouk Abdulmutallab to destroy Northwest flight 253 as it prepared to land in Detroit on Christmas day, airports around the world are considering mandatory installations of full-body (whole body) scanners including backscatter systems. Numerous media organizations have reported on whether radiation exposure from these systems poses a health risk to those who are scanned.
Representatives from the American College of Radiology outlined strategies for transforming computed tomography technology and its use to minimize medical radiation exposure today at the National Institutes of Health "Summit to Focus on Management of Radiation Dose in Computerized Tomography – Emphasis Toward the Sub-mSv CT Exam."
